Imagine that you take a road trip from a to d, but you have to do it in segments. let’s say the distance from a to b is 145 miles; from b to c is 160 miles, and c to d is 115 miles. it takes you 6 hours to drive from a to d. what was your average speed (in miles per hour) during your trip from a to d? (hint: how many miles did you drive from a to d? then divide the total miles by the number of hours).
a. 50
b. 60
c. 70
d. 80
e. 90

C

Step-by-step explanation:

The average speed can be obtained by adding the distances together and dividing by the total amount of time.

The total distance the man traveled from A to D is the addition of the distance from A to B plus the distance from B to C plus the distance from C to D. This is mathematically equal to 145 + 160 + 115 = 420 miles.

Dividing 420 miles by 6 = 70 miles per hour

(12x2-2x+2)

Step-by-step explanation:

(12x)(x)+(5)(x)+-7x+2

12x2+5x+-7x+2

(12x2)+(5x+-7x)+(2)

12x2+-2x+2
